Abstract:
A self-adaptive control miniature motor comprises a driving unit (200), a mover (300) and a self-adaptive control unit (100). The driving unit comprises a fixed stator and a movable vibration block, and provides the driving force for the reciprocating motion of the mover through the interaction between the stator and the vibration block. The mover is a forced vibration part, and is driven by the movable vibration block of the driving unit to do the reciprocating motion. The self-adaptive control unit is used for controlling a motion state of the mover in real time by adjusting a force applied on the mover, based on a feedback information of the motion state of the mover. The self-adaptive control miniature motor, by combining the motor hardware with a control circuit, facilitates real-time adjustment of the magnetic field intensity in the motor, thus improving the stability of the vibration of the motor.
